abstract: Surgical-site infections and postoperative complications: agreement between the Danish Gynecological Cancer Database and a randomized clinical trial (patient safety)
Conclusions. The randomized trial reported significantly more surgical-site infections than the clinical database. The DGCD reported only 50% of the deep and organ-space infections, and hence, the low-overall agreement indicates a need for more careful database registration.

abstract: Phase II study evaluating consolidation whole abdominal intensity-modulated radiotherapy (IMRT) in patients with advanced ovarian cancer stage FIGO III - The OVAR-IMRT-02 Study
BACKGROUND:
".... Recurrences of the disease occur mostly intraperitoneally. Ovarian cancer is a radiosensitive tumor, so that the use of whole abdominal radiotherapy (WAR) as a consolidation therapy would appear to be a logical strategy. WAR used to be the standard treatment after surgery before the chemotherapy era; however, it has been almost totally excluded from the treatment of ovarian cancer during the past decade because of its high toxicity. Modern intensity-modulated radiation therapy (IMRT) has the potential of sparing organs at risk like kidneys, liver, and bone marrow while still adequately covering the peritoneal cavity with a homogenous dose. Our previous phase I study showed for the first time the clinical feasibility of intensity-modulated WAR and pointed out promising results concerning treatment tolerance. The current phase-II study succeeds to the phase-I study to further evaluate the toxicity of this new treatment. Methods / design: The OVAR-IMRT-02 study is a single-center one arm phase-II trial. Thirty seven patients with optimally debulked ovarian cancer stage FIGO III having a complete remission after chemotherapy will be treated with intensity-modulated WAR as a consolidation therapy. A total dose of 30 Gy in 20 fractions of 1.5 Gy will be applied to the entire peritoneal cavity including the liver surface and the pelvic and para-aortic node regions. Organ at risk are kidneys, liver (except the 1cm-outer border), heart, vertebral bodies and pelvic bones. Primary endpoint is tolerability; secondary objectives are toxicity, quality of life, progression-free and overall survival.
DISCUSSION: Intensity-modulated WAR provides a new promising option in the consolidation treatment of ovarian carcinoma in patients with a complete pathologic remission after adjuvant chemotherapy. Further consequent studies will be needed to enable firm conclusions regarding the value of consolidation radiotherapy within the multimodal treatment of advanced ovarian cancer. Trial registration: NCT01180504.

abstract: Phase II trial of combretastatin A4 phosphate, carboplatin, and paclitaxel in patients with platinum-resistant ovarian cancer
Note: searching blog for A4 will provide further research specific to clear cell/A4
CONCLUSIONS: The addition of CA4P to paclitaxel and carboplatin is well tolerated and appears to produce a higher response rate in this patient population than if the chemotherapy was given without CA4P. A planned randomised trial will test this hypothesis.

abstract: Indication for oophorectomy during cytoreduction for intraperitoneal metastatic spread of colorectal or appendiceal origin
BACKGROUND: The incidence of ovarian metastases at the time of peritoneal carcinomatosis, and the influence of such metastases on survival after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), are unknown.
CONCLUSION: When peritoneal carcinomatosis of colorectal or appendiceal origin is confirmed, at least 52 per cent of ovaries will have synchronous metastases. Disease-free survival after a HIPEC procedure for PMCA or DPAM is significantly lower in women with ovarian metastases. Oophorectomy during CRS for peritoneal carcinomatosis should be strongly considered.

abstract: Whole abdominopelvic radiotherapy using intensity-modulated arc therapy in the palliative treatment of chemotherapy-resistant ovarian cancer with bulky peritoneal disease
CONCLUSION: WAPRT delivered using intensity-modulated arc therapy offers important palliation in the case of peritoneal metastatic ovarian cancer. WAPRT resolved intestinal obstruction for a substantial period.

abstract: Role of adjuvant radiotherapy in granulosa cell tumors of the ovary
PURPOSE: To review the role of adjuvant radiotherapy (RT) in the outcome and recurrence patterns of granulosa cell tumors (GCTs) of the ovary.
CONCLUSION: Ovarian GCTs can be indolent, with patients achieving long-term survival. In our series, adjuvant RT resulted in a significantly longer DFS. Ideally, randomized trials with long-term follow-up are needed to define the role of adjuvant RT for ovarian GCTs.
